curley can you call your vet's office and askunless your dog is allergice to onions, it usually takes a large amount to be lethal(but that also depends on your dog's weight and health coindition too)I hope it is not enough to maka\e him sick.

What I'm reading online says the amount of onion determines the toxicity. If it were me I'd make her throw up. It says the symptoms can take a couple of days before you realize anything is wrong, and then it sounds like it's too late.

It causes a type of anemia where there's a bubble in the red blood cell weakening it. If too many of the RBCs pop it kills the dog.

Ok, the vet said it isn't enough to be considered lethal for her size, but to keep an eye on her and bring her in if she starts acting odd. I tried to gag her and the peroxide trick at his suggestions, but no onions came up. So, I'm monitoring her until I leave for work and then my roommie will be watching her. I swear this dog is going to give me a heart attack one day with the things she thinks is ok to eat.

These vegetables and herbs can cause gastrointestinal irritation and could lead to red blood cell damage. Although cats are more susceptible, dogs are also at risk if a large enough amount is consumed. Toxicity is normally diagnosed through history, clinical signs and microscopic confirmation of Heinz bodies. An occasional low dose, such as what might be found in pet foods or treats, likely will not cause a problem, but we recommend that you do NOT give your pets large quantities of these foods."

"Onions, Garlic, Chives An occasional low dose, such as what might be found in pet foods or treats, likely will not cause a problem, "

WTF, why would they put something that is a known toxin into their food or treats??

Good question. I often come across "all natural" pet shampoos that contain essential oils, which are highly toxic to cats. I guess the fact is the manufacturers don't care if they can make a buck off it. Look at all the toxic chemicals in human products.

Thanks all for the info. This is day 2 and curly is acting "normal" for her spaz self. Monitoring her for the next couple days to be sure. My vet was really nice about it, and said to call any hour if she started acting different.
